The work is devoted to the problem of increasing efficiency of power gas turbine units (microturbines). One of ways to improve efficiency is to increase gas temperature in front of the turbine. Cooling of gas turbine elements is difficult. One of the solutions to the problem may be the method of thermal emission cooling. The purpose of this work is to estimate the potential effect of thermal emission cooling of turbine blades on efficiency.

Abstract:
The problems faced by designers of micro-turbines are connected with a very small volume flow rate of working media which leads to small blade heights and a high rotor speed. In the case of gas turbines this limitation can be overcome by the application of a closed cycle with very low pressure at the compressor inlet (lower than atmospheric pressure). In this way we may apply a micro gas turbine unit of accepted efficiency to work in a similar range of temperatures and the same pressure ratios, but in the range of smaller pressure values and smaller mass flow rate. Thus, we can obtain a gas tu

Abstract:
The W501D5, W501D5A, and SGT6-3000E gas turbines have been in operation for almost 30 years and continue to be a reliable workhorse for many power suppliers. As these units age, operating costs and power production become key drivers in order to maximize profits and improve dispatch rates. Performance upgrades for this mature frame allows customers to benefit from proven technology used in advanced frames in order to lower their overall combustion turbine operating costs and provide improved thermal performance. The W501D5 and W501D5A fleet contain approximately 150 units with the fleet leader

Abstract:
A study of the remaining rotor life of gas turbines (or combustion turbines) used in the oil and gas industry was performed by Gas Turbine Materials Associates (GTMA). The study focused upon analytical methods of determining the remaining rotor life using a reduced data set, where not all of the operating data is known. As part of this study, a survey of oil and gas users was performed on their rotor life. An analytical model and methodology for determining the remaining rotor life was developed. This model and methodology was applied to the GE MS5002 gas turbine. By using this model for a PRC

Abstract:
When natural gas is combusted, formaldehyde is formed as an intermediate product as methane is converted to CO2 during combustion. Formaldehyde is regulated by the U.S. EPA as a hazardous air pollutant (HAP) under National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations, and both turbines and reciprocating engines are listed source categories where EPA is required to develop regulations. NESHAPs have been adopted for natural gas-fired combustion turbines and reciprocating internal combustion engines (RICE), with initial regulations in 2004 that included a 91 parts per bill

Full text
Abstract:
Gas turbine engines are in common use in the Gas Pipeline industry to drive gas compressors in compression facilities. One of the major cost factors in the operation of these turbines is the repair or replacement of the hot section components. Technology that can extend the operational life of these components, or increase the ability to repair these components, is of immediate financial and operational benefit to members of PRCI. The RB211 gas turbine engine is commonly used in compression facilities. The life of the model 24C HP turbine blades is currently inadequate, leading to early replac

Full text
Abstract:
Inlet air filters are widely used to remove solids and liquid droplets from the ambient air before it enters the compressor of a gas turbine. Clean inlet air provides many advantages: Less corrosion of the compressor and of gas-path hot parts, such as the turbine, decreased compressor fouling, less erosion of the compressor bladeThese in turn prevent deterioration of output and heat rate, and reduce maintenance costs. Compressor fouling is caused by the ingestion of substances that deposit and adhere to blade surfaces, resulting in reduced aerodynamic efficiency and decreased available output.

Abstract:
Air pollution has become a major public issue and it is now evident that unburned hydrocarbons, CO, and NOx must meet increasingly restrictive standards. The emissions of nitrogen oxides by gas turbines are of concern because of their high toxicity and their role in the formation of photochemical smog. The formation of NOx occurs in a gas-fired gas turbine when combustion temperatures exceed a critical level for sufficient time to allow atmospheric nitrogen and oxygen to combine. For those gas turbine applications where steam or ultra-pure water are readily available, then steam or water injec

Full text
Abstract:
More cost-effective high-pressure calibrations could be provided by using inert gas instead of natural gas. However, the impact of the different gas properties must be investigated to reduce any bias that could result in substantial financial risks for trading large volumes of gases. The research objective was to develop and test a transfer model for turbine flowmeters that could be used to translate a calibration in an inert gas to be suitable for use in natural gas applications.

Abstract:
Since formaldehyde is ubiquitous (e.g., naturally formed through atmospheric chemistry even if not directly emitted), there is also the potential that atmospheric levels and atmospheric chemistry are not adequately understood.� That avenue of investigation may provide important information that could be important in assessing formaldehyde health risk, source contribution, and ultimately regulatory criteria for gas-fired combustion sources.� In 2002 and 2003, the pipeline industry conducted turbine formaldehyde testing using refined FTIR methods and a dedicated measurement system, which indicat
